Title: Discharge lamp lighting device
Inventor: ITO KAZUHIKO
IPC: H05B41/24
Filed: 1987-12-24
Abstract: PURPOSE:To prevent an abnormal oscillation or an error operation of a circuit by providing a short circuit transistor and a Zener diode parallel to a driving inductance 12. CONSTITUTION:A Zener diode 21 is connected to let a base current flow between the collector bases of a transistor 18 through a Zener voltage. At the base current discontinuous time when a transistor 6 is switched on, the surge voltage generated at an inductance 12 is also increased, and it is applied between base emitters of the transistor 6 in the regular direction being liable to generate an error operation, but the surge voltage is suppressed by a transistor 18 and the diode 21 parallel to the inductance 12 with its Zener voltage. Furthermore, even though the potential at the capacitor 13 side of the inductance 12 is raised when the transistor 6 is turned on, the turning-on is prevented and the error operation of the circuit is avoided since the diode 21 is connected in the regular direction between the collector emitters of the transistor 18.

Title: Guide system for mechanical press dynamic balancer, and mechanical press
Inventor: BRADLEY A BURNS
IPC: B30B15/00
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent baking of a guide system and excessive vibration of a press, and improve quality of a molding product by arranging a balancer guide post and a weight guide in an opening of a dynamic balancer. SOLUTION: A balancer weight 40 is reciprocated along a long axis of a guide post and a guide post 48 while a press is working. A U-shaped weight guide 54 prevents the balancer weight 40 from rotating around the balancer guide post and the guide post 48, and also prevents vibration from being applied to a press due to the reciprocation movement. A clearance between the weight guide 54 and the guide post 48 due to a gap 58 provides tolerance of thermal expansion to a press constitution element at the operation time. The weight guide 54 allows elongation difference due to the heat between the balancer weight 40 and a press frame. A clearance between a bearing face 52 and the guide post 48 formed by the weight guide 54 reduces vibrations caused by the reciprocation movement of the balancer weight 40.

Abstract: PURPOSE:To prevent the power source from being cut off automatically in the case when it is unnecessary by permitting or inhibiting a cut-off control of the power source corresponding to the duration of a prescribed operating state in accordance with a difference of the power source means used for a feed. CONSTITUTION:When a commercial AC power source supply is executed from a power source jack 3, a voltage of a line l3 becomes about 8V, an output of a voltage detector 2 becomes a logical level '1', and when an AC adaptor is not connected to the power source jack 3 and a feed is executed from only a battery 6, the voltage of the line l3 becomes under 6V, and the output of the voltage detector 2 becomes a logical level '0'. A CPU 4 discriminates this logical level, and when the feed is executed from only the battery 6, an auto power-off signal is sent to a power source control part 1, and an auto power-off processing is executed. On the other hand, when a feed is executed from a commercial AC power source, the auto power-off processing is inhibited. In such a way, it does not occur that auto power-off is executed at the time when it is unnecessary.
